Graphing a quadratic by completing the square to use vertex form

The video tutorial covers solving quadratic equations by completing the square to convert them into vertex form. It explains the process of creating a perfect square trinomial, factoring it into a binomial squared, and graphing the resulting function. The tutorial also discusses determining the vertex, domain, and range of the function.

Describe the steps to complete the square for the expression y = x^2 - 6x + 2.
